Wellsent
Our client wanted control over email warm-up and the handling of its mailbox addresses. We built Wellsent as a self-hosted platform with a dedicated receiving pool, configurable sending schedules, template checks and domain diagnostics.
Taking control of the warm-up process
Our client did not want to entrust mailbox addresses and the warm-up process to an outsourced service. It wanted to control how sending worked and how those addresses were handled. We built Wellsent around a self-hosted installation and a dedicated pool of receiving inboxes, with the sending schedules and delivery checks available to inspect.
The client can configure the process and review the mailbox history within the platform. That control comes with responsibility for running the infrastructure. Separate workspaces support multiple client accounts, while configurable scoring rules let the team adjust how it reviews templates.
A controlled sending ramp
Connected mailboxes follow a sixteen-day schedule that starts with ten sends and rises to the configured full volume. Messages are exchanged with the receiving pool, with AI-generated replies kept in the conversation thread. A sweep every five minutes records where warm-up mail arrived and moves messages found in spam back to the inbox.
Testing a template before outreach
We combined content checks with delivery observations. The editor flags features such as repeated text, a high number of links and terms associated with spam. A template check then sends the draft from the connected mailbox to pool addresses at several providers and reports where each copy landed. This gives the sender evidence to review before outreach, while placement can still vary by recipient.
A specific issue to investigate
The domain dashboard names conditions such as a missing email-authentication record or a blocklisted sending domain. That detail gives the team a place to start investigating, alongside the template results and mailbox history.
